Video of the Swiss on Everest in 1952

While Hillary and Tenzing's successful ascent on May 29, 1953, is quite well known, oft-forgotten is the Swiss in 1952. In that year, Raymond Lambert and a young Sherpa - Tenzing Norgay - made it within 300 meters of the summit of Everest before turning back due to weather and oxygen issues. An amazing attempt, and nearly successful.
